ci(1979): arm the stale sweep — .github joins the wave, and the flip lands last

repo-inventory.yml

@@ -427,24 +427,6 @@ shared_reasons:
     in the sense the sweep measures -- it is a decision nobody has taken, which is what the board
     card is for (.github#138). Unaffected by backend#1979: the reason was never about which
     columns the sweep could see.

-    STAGED, NOT PARKED (backend#1979). stale-backlog.yml is mid-migration from a 16-way COPY to
-    a reusable + thin callers, because the fix it blocks needs board awareness and board
-    awareness needs a script -- which cannot be maintained as sixteen byte-identical copies
-    (backend#1597 item 1). Declared `exempt` only while the caller PRs are in flight: flipping
-    it to `required` before a repo's caller lands would redden the org audit for every repo
-    still waiting, which is the drift window made to look permanent. The final PR of the sweep
-    flips every one of these to `required`; if this anchor is still here after that, it has
-    become the same finding as wip_limit_check_has_no_callers -- a reusable that shipped and was
-    never wired up, with a written excuse. Treat it as a defect then, not a justification.
-    .github IS IN THE WAVE LIKE EVERY OTHER REPO, and its caller is deliberately NOT in the PR
-    that lands the reusable (Bugbot, .github#288). `exempt` + a caller on the audited branch is
-    itself a finding (caller-drift.py:2260), and a caller added in this repo goes green
-    pre-merge only because .github's own callers are read from develop over the API rather than
-    from the checkout -- the awkwardness caller-drift's docstring already documents. So it would
-    have merged green and reddened the very next audit, which is the outage this exemption
-    exists to prevent. The cost is that .github is unswept until its caller lands with the
-    others; the sweep is weekly and the reusable has never run, so nothing regresses.

     single-branch repo: `main` is the only integration branch, so there is no `develop` to protect.
     Structural, not a gap. Precise staleness rule, because an earlier draft of this note overstated
